Anthony Alcock has sent me another translation from Coptic. There is a collection of 10th century Coptic poems, which were published in Oriens Christianus (the volumes are online at Archive.org). One of these is about the martyr Archellites. Here it is:

There is no historical content to this, but it is useful to have this material in English – thank you!

I remember long ago transcribing the English translation of the Legend of Hilaria, a story about a female monk, who supposedly lived in the late 5th century, in the time of the Emperor Zeno. There is also a Legend of Archellites. In fact a translation of these two prose narratives, and the Coptic version of the Legend of the Seven Sleepers, was made in 1947 by James Drescher.[1] A rather clumsy site has the book here.

UPDATE: There is a useful short article on Coptic poetry online here. It is only two pages long. It comes from the Coptic Encyclopedia.
